Hi everyone. I'm new at this list and with PostGIS. My english isn't 
very good, sorry.
I have to two multilinestrings that are almost perpendicular, but they 
don't intersect. What i want is to enlarge one of them so it intersects 
with the other one, and then obtaining the intersection point, and 
splitting the line with the intersection in two from that intercection 

    Line to split:
         MULTILINESTRING ((439889.59 4474591.929, 439976.17 4474582.01))

    Line wich should intersect whith it:
         MULTILINESTRING ((439923.24 4474588.07, 439924.28 4474546.04, 
439932.48 4474500, 439937.73 4474470.48))

    Distance between them, they are almost touching:

Thanks for your help. And sorry again for my english:
